Abstract

Instrumentation system in a company has many developments to supplement the income of company, it causes a lot of research conducted with consideration of the concept of zero inventory, one of the companies that need those concepts are mining, the company may be in terms of process monitoring and control on the fuel tank, so it brings the number of the volume of fuel that is accurate and charging optimally.
At the end of this task will be created tank prototype using potensio multitrun as a sensor, the sensor detects the tank with the volume given the vest on the one hand and the weight on the other side, so that when the volume of fuel is reduced or increased bouy and ballast will change the position of the third potensio the rotaring. The data obtained from potensio was arrested by the ADC on the arduino and converted to a unit volume of fuel, after that data sent over the internet to the web as the ground sector by using the raspberry pi which is connected to the modem, the data is sent to the web application was then made as information system management.
Calculation of the volume of the tank using the sensor potensio multitrun have 97,63% percentage of success. Monitoring the volume of fuel in the web applications in the from of an information management system has been successfully up and running smoothly. Although the delivery of the data to the web occurring error, sometimes this happens because internet connections are less stable.
